China’s police have a new weapon in their surveillance arsenal: sunglasses with built-in facial recognition. According to reports from local media, the glasses are being tested at train stations in the “emerging megacity” of Zhengzhou, where they’ll be used to scan travelers during the upcoming Lunar New Year migration. This is a period of extremely busy holiday travel, often described as the largest human migration event on Earth, and police say the sunglasses have already been used to capture seven suspects wanted in major cases, as well as 26 individuals traveling under false identities.
